Data collection Data about hospitalizations and emergency department admission were collected in real time because the patients were trained to notify these circumstances and the daily follow-up permitted to know the situation of every patient in every moment. Moreover if a patient did not send the daily data the system generated an alarm resulting in a phone call from the nurse to know the reason why the information had not been sent. Besides, in every patient a review of hospital and emergency department admission was carried out at the end of every year.
